v.AUTOMATIC LUBRICATI Gr IPEVICE.

To all 'whom t may concern.' 4

Be it `known that I, EDWARD H. NELSON, a citizenof the United States,residing at'v y per end inside the container 1.

`when it is vibrated made of glass xalesburg, in the county of Knox andState of Illinois, have invented certain new and Improvements inAutomatic Lubricating Devices; and I do hereby declare the following tobe a full, clear, and eXact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

-This invention relates to automatic lubricating devices, and one ofthe'principal objectsA of the invention is to provide a lubricating cupadapted to be secured 4to any part of a machine and having ay pin orplunger mounted in the cup in such manner that by the movement of themachine, the lubricant will be fed down the outer side of the plunger'orpin and applied to the shaft or other bearing'.

Another` object of the invention'is to provide an oil cup with a plungeror pin of smaller diameter than the bore in which it l fit-s to feed oilby vibration or jarring of the V mechanism to 1v hich it is applied forfeeding o1l to a bearing.

e foregoing or other obgects may be at- -tained by means' of theconstruction illustrated 1n the accompanying drawing, in which, A

Figure 1 is a vertical section through aV e in accordance with thisinvention, Fig. 2 isa side elevation of the same showing the oil cup indotted lines'.

Referring to the'draWing, the numeral 1 designates an oilcontainerwhich' may be having its upper' and lower ends opened andprovided with an annular flange 2 at its'. upper side and a similarflange 3 at its lower end. Fitted in the openings in the oil container 1is a tubev 4, said tube having at its lower end interior screw threads 5to fit a threaded plug G, said plug having an oil duct 7 therein, andbeing iitted to the oil container 1 by means of a rubber gasket 8 andalso provided with screw threads 9 for attachment to any part of amachine -at the )earing of a shaft. A plunger 10 passes through the oilduct 7, eter than said ducts, and is provided With a flattened upper end11. The tube-4 is provided with a feeding opening 12 for the oil, nearits lowr'end and a slot 13 near its up- Specification of Letters Patent.Application mea December 12, 1914. serial No. 876,877.

A 'tube 14 is'itted in the tube 4 andsaid tube 14 is provided with aperforation or oil duct 12a at its lower end. The inner tube 14 ismounted 'to rotate within the tube 4, and at its upper endis providedwith e knurled head 15, said head being provided With a downwardlyextending stop lug 16. The lug 16 is mounted in a. recess or slot 17 inthe upper end of the tube'4. The tube 4 is secured to the container latits upper end by 'means of Washers 18 and a gasket 19. A cap 20.15fitted to the upper end of the tube 4 and serves to'compress the washersand gaskets to make a tight joint at the top of the container 1.

2. A lubricating device comprising' an oil container, a plug fitted inthe lower end of said container and provided with a bore, and a feedingpin or plunger mounted in the bore and being of smaller diameter thansaid bore, and a tube extending through the container and provided witha rotary inner tube having openings for filling the oil container andfor feeding the oil to said pin, 'a lug on said inner tube, a recessformed in the outer tube, andkmeans for turning the inner tuberelatively to the outer tube to ll the container and to regulate the Howof oil from the container to said pin or plunger.

In testimony whereof I affix my signature in presence of two Witnesses.
